Silicon based life, has anybody tried this? (5)

In decades past there was considerable theoretical interest in the idea of silicon-based life, but it turns out that silicon does not behave quite exactly like carbon. Silicon-silicon bonds are not as strong as carbon-carbon bonds, so the sort of enormous and complex carbon-based molecules required by life as we know it (proteins, etc.) are unstable when silicon is substituted for carbon.

This is not to say that life evolving in an environment where soluble silicate and silane compounds were common could not have carbon-based biochemistry with bits of silicon-based compounds here and there that might have unusual and useful properties, but that is just speculation.
